Custom Compiler Tutorial

This document provides a tutorial on using a custom compiler with a 14nm process in PrimeWave. It outlines the steps to include library definitions, create a new library with the target technology, build a schematic with cells from the library, run simulations in PrimeWave by setting up the design, simulator, variables, analyses, model files and outputs, and annotating the operating point results on the schematic. The tutorial covers key tools, menus and settings for library management, schematic design entry, simulation setup and viewing simulation waveforms and results.
